PIX routing possibility

[mastechnology]

Dear All,

I have a client with the attached Network topolog file. He wants to

install his PIX firewall in the position showed in the topology file…

His request is to route the internal traffic between his branches and internet using his PIX firewall….

Actually I did not know if it's possible to route his traffic from B1, B2

and B3 to internet and back to the mail VPN device at HQ by PIX Or no..

Can any one of you help me to make his network work properly and can any

traffic to the internet from any Branch go smoothly and get back to his

source IP???

I tried to make something like route inside 192.168.0.0 255.255.0.0

192.168.18.1 1 with no hope… please help me to fix this issue if possible…

Thanks in advance…

Best regards,,,

To route this correctly, you would need a route for each remote network:

route inside 192.168.19.0 255.255.255.0 192.168.18.1

route inside 192.168.20.0 255.255.255.0 192.168.18.1

route inside 192.168.21.0 255.255.255.0 192.168.18.1

and a default route for the Internet:

route outside 0.0.0.0 0.0.0.0 (ISP Gateway IP address)

If the rest of the PIX config is correct, this should work.
